Abstract Scope |
Copper perovskites are synthesized via wet-chemical processes with substituted organic cations in the A-site to explore the effects of varied chain length, isomerism and secondary amine precursors on electrical output in PDMS composites. Among the organic cations used are methylamine(MA), butylamine(BA), isobutylamine(IBA), dibenzylethylenediamene(DBED), and hexylamine(HA). The different traits among these precursors has an effect of producing varied particle size, particle dimension and different rates of agglomeration. These perovskites are then suspended in a PDMS film matrix and fashioned into sensor devices where their electronic outputs are tested under mechanical stress using an oscilloscope to compare open circuit voltages. The perovskite powders were also subjected to XRD, XRF, SEM, TGA, DSC and AFM characterization techniques. A suitable perovskite for high electronic output is then determined and ranked among each other. These copper perovskites offer insight, revealing characteristics that could lead to phasing out the use of leaded halide perovskites used today. |
